Forces review and CER practice

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

Front

What is impact force?

Back

Impact force is the force exerted when two objects collide.

Front

How does height affect impact force?

Back

Increasing the height from which an object is dropped increases its impact force.

Front

What is elasticity?

Back

Elasticity is the ability of a material to return to its original shape after being stretched or compressed.

Front

Why is elasticity important in collisions?

Back

Elasticity helps reduce impact force by allowing materials to absorb energy during a collision.

Front

How does surface area affect force distribution?

Back

A larger surface area distributes the force more evenly upon impact.

Front

What happens to motion if mass is doubled while force remains constant?

Back

The motion of the object will decrease.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, force equals mass times acceleration (F = ma).

Front

What is inertia?

Back

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

Front

What is the effect of friction on motion?

Back

Friction opposes motion, making it harder for objects to move.
