Force and Motion

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is measured in units like miles per hour (mph) or meters per second (m/s).

Front

What happens when two forces acting on an object are balanced?

Back

When two forces are balanced, they cancel each other out, resulting in no change in the object's motion.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, change direction, or change shape. It occurs when the net force acting on an object is not zero.

Front

What is friction?

Back

Friction is a force that opposes the motion of objects that are in contact with each other. It acts parallel to the surfaces in contact.

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is the effect of an unbalanced force on a moving object?

Back

An unbalanced force will cause the object to accelerate in the direction of the force.

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is the relationship between force and motion?

Back

Force is a push or pull that can cause an object to move, stop, or change direction. Motion is the change in position of an object.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.
