What causes an object to change speed or direction?

Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. So forces cause acceleration.

What force causes a moving object to speed up?

LAW 2 – Forces make things speed up (or accelerate). When a force pushes or pulls the object, the object will move in the direction of the force. The bigger the force, and the lighter the object, the greater the acceleration.

What causes an object to move speed up slow down and stop or change direction?

For stationary objects and objects moving with a steady speed in a straight line, all the forces cancel each other out, i.e. they are balanced. If the forces are not balanced then the motion of the object changes. It may speed up, slow down and/or change direction.

What will happen to the speed of a moving object when we apply force in direction of motion?

If the force applied on the object is in the direction of its motion, the speed of the object increases. If the force is applied in the direction opposite to the direction of motion, then it results in a decrease in the speed of the object. Let us consider some more examples.

How can we reduce the speed of a moving object?

Answer: If force is applied in the direction opposite to the direction of the motion , it results in a decrease in the speed of the object.

Can a less massive object have more momentum than a more massive object?

A less massive object can never have more momentum than a more massive object. Two identical objects are moving in opposite directions at the same speed. The forward moving object will have the greatest momentum.

Does a stationary object have inertia?

Inertia is a force which keeps stationary objects at rest and moving objects in motion at constant velocity. Inertia is a force which brings all objects to a rest position. All objects have inertia. Fast-moving objects have more inertia than slow-moving objects.

When an object speeds up does it gain momentum?

The momentum of an object can change. Two objects with the same mass will always have the same momentum. Not all moving objects have momentum. When an object speeds up it gains momentum.

How can a more massive object have the same kinetic energy as a less massive object?

This is conservation of momentum. Velocity is the influencing factor in momentum. Also, inelastic collision means that the objects will not bounce off after collision. Therefore, the speed of the more massive object will be the same as the speed of the less-massive object because of transfer of kinetic energy.

How do you know if an object has more kinetic energy?

Anytime matter is in motion it has kinetic energy. The faster an object moves, the more kinetic energy it has. The more mass an object has, the more kinetic energy it has. According to this equation, what effects K.E. more the mass or the velocity?

How do you know if an object has more potential energy?

The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds.

Can an object have more than one form of energy?

While energy can come in many different types, there are only two main forms of energy: kinetic energy and potential energy. These energies are found in all objects. If an object is in motion (i.e. moving), it is said to have kinetic energy.

What are the factors affecting the kinetic energy of an object?

There are two factors that affect how much kinetic energy a moving object will have: mass and speed.

What are the factors that influence the kinetic energy of this airplane?

The amount of Kinetic Energy that an object possesses is dependent on two factors: mass and velocity. Both of these factors are directly proportional to the kinetic energy.

What is the kinetic energy of a 100 kg object that is moving with a speed of 12.5m S?

= 7,812.5 joules Your attachment is way out of focus, and impossible to read.

What happens to the kinetic energy of a moving object if its velocity is doubled?

Answer. If velocity is doubled, Kinetic Energy increases by 4 times. Kinetic energy of a body is the energy possessed by it, by virtue of its motion, i.e. if the body is moving it will always have kinetic energy.
