Forces and Motion 5

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is described by Newton's First Law of Motion.

Front

What does the term 'average speed' mean?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

What is a contact force?

Back

A contact force is a force that acts at the point of contact between two objects, such as friction.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it is in contact with another surface.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the difference between constant speed and average speed?

Back

Constant speed means the speed does not change over time, while average speed is the total distance divided by total time.

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, such as the Earth and an object.

Front

What is the role of friction in motion?

Back

Friction can slow down or stop the motion of an object, making it harder to move.
