Forces and Motion Flashcard

Front

What is friction?

Back

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

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force in SI is the Newton (N).

Front

What is the formula for calculating speed?

Back

Front

What happens to two objects of different masses dropped from the same height in a vacuum?

Back

Both objects will hit the ground at the same time.

Front

What is the relationship between mass and weight?

Back

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over 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 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 effect of surface texture on friction?

Back

Different surface textures can increase or decrease the amount of friction between two surfaces.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.
