Front

What direction must a force be exerted to speed up an object?

Back

The force must be exerted in the same direction as the object's motion.

Front

If two objects collide with the same force but have different masses, how will their changes in velocity compare?

Back

Their changes in velocity will be different.

Front

What is the effect of a balanced force on the motion of an object?

Back

A balanced force does not change the motion of an object.

Front

What happens to the change in velocity when a stronger force is exerted on an object compared to a weaker force?

Back

You will see a greater change in velocity.

Front

What force holds us to the Earth's surface?

Back

Gravity.

Front

Define force in the context of motion.

Back

A push or pull that can change the motion of an object.

Front

What is mass?

Back

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

Front

Explain the difference between balanced and unbalanced forces.

Back

Balanced forces do not change an object's motion, while unbalanced forces do.

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

As mass increases, acceleration decreases if the force is constant.

Front

What is inertia?

Back

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