Forces and Motion

Front

What is the relationship between mass and force in terms of acceleration?

Back

The greater the mass of an object, the greater the amount of force is needed to make it accelerate.

Front

What force makes it harder for objects to move down a slope?

Back

Friction is the force that opposes motion and makes it harder for objects to move down a slope.

Front

What force is responsible for slowing down a rolling ball on the ground?

Back

Friction is the force that slows down a rolling ball.

Front

What type of force is acting on an airplane during takeoff?

Back

An unbalanced force is acting on an airplane during takeoff.

Front

If an object is speeding up or slowing down, what can be said about the forces acting on it?

Back

The forces acting on it will be unbalanced.

Front

Define force in the context of motion.

Back

Force is a push or pull that can cause an object to accelerate.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change the motion of an object, while unbalanced forces cause an object to accelerate.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the formula for calculating force?

Back

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