Forces and Motion P.1.1 and P.1.2

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 gravity?

Back

Gravity is a force that pulls objects toward each other, such as the force that pulls objects toward the Earth.

Front

How does mass affect motion?

Back

An increase in mass generally makes it harder to accelerate an object, which can decrease its speed.

Front

What is speed?

Back

Speed is the distance an object travels in a certain amount of time, usually measured in meters per second (m/s).

Front

What happens to a ball on a ramp due to gravity?

Back

The ball will roll down the ramp because gravity pulls it downward.

Front

What is the formula to calculate speed?

Back

Speed = Distance ÷ Time.

Front

What is the effect of a rough surface on friction?

Back

A rough surface increases friction, making it harder for objects to slide over it.

Front

What is the relationship between mass and gravity?

Back

The greater the mass of an object, the stronger the gravitational pull it exerts.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does friction affect the speed of a moving object?

Back

Friction slows down the speed of a moving object.
