Forces and motion

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What should a baseball pitcher do to make a ball reach the catcher?

Back

Increase the force used when throwing the ball.

Front

How can you increase the acceleration of an object?

Back

By decreasing its mass.

Front

Which type of force resists motion?

Back

Friction.

Front

What does a graph showing a straight line represent?

Back

Constant Speed.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is friction?

Back

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

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a).
