What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. If an object is speeding up, it is said to be accelerating.

Front

What does a steeper line on a distance-time graph indicate?

Back

A steeper line on a distance-time graph indicates that the speed is faster.

Front

How does the surface texture affect friction?

Back

Rough surfaces have greater friction compared to smoother surfaces.

Front

What would happen to an object in motion without friction?

Back

Without friction, an object in motion would never stop.

Front

What does a horizontal line on a speed-time graph represent?

Back

A horizontal line on a speed-time graph indicates that the object is moving at a constant speed.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between surfaces.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

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 at a constant velocity unless acted upon by a net external force.
