What happens to an object in motion if no net force acts on it?
It comes to a stop immediately.
It continues to move at a constant velocity.
It accelerates in the direction of motion.
It changes direction randomly.
What is Newton's 3rd law of motion?
For every action, there is an equal and opposite reaction.
An object in motion stays in motion unless acted upon by an external force.
The force of gravity is proportional to the mass of the objects involved.
The acceleration of an object is directly proportional to the net force acting on it.
If weigh is a force can you use F=ma to calculate it?
No, F=ma is only for mass and velocity.
Yes, but you don't need acceleration due to gravity.
Yes, you will also need acceleration due to gravity for the a variable in F=ma
No, weight is not a force.
What is a force?
A force is a push or pull on an object.
A force is a type of energy.
A force is a measure of mass.
A force is a change in velocity.
In the formula for calculating force what does each letter stand for (F= ma)?
Force (F) = mass (m) × acceleration (a)
Force (F) = mass (m) + acceleration (a)
Force (F) = mass (m) - acceleration (a)
Force (F) = mass (m) / acceleration (a)
What is the effect of friction on motion?
Friction has no effect on motion.
Friction opposes motion and can cause an object to slow down or stop.
Friction increases the speed of an object.
Friction only affects objects in water.
What is an example of inertia in everyday life?
A passenger lurches forward in a car when it suddenly stops.
A ball rolls down a hill when pushed.
A person feels heavier when jumping off a diving board.
A book remains on a table until someone picks it up.
How does mass affect force in a collision?
The player with greater mass will exert more force during a collision.
The player with less mass will exert more force during a collision.
Mass has no effect on the force exerted during a collision.
Force is only dependent on speed, not mass.
draw out this force diagram to solve: if a set of books experiences a force to the right of 7N and a force to the left of 10 N. In what direction (if any) will the books move?
with 3 N to the right
with 3 N to the left
with no movement
with 7 N to the left
What is the unit of force?
Pound (lb)
Kilogram (kg)
Newton (N)
Joule (J)
Momentum is ______ in motion.
mass
velocity
force
acceleration
What is an example of Newton's 3rd law of motion?
When you jump off a small boat, the boat moves backward.
A ball rolling down a hill accelerates due to gravity.
A car accelerates when the driver presses the gas pedal.
A person pushes against a wall and the wall pushes back.
What is inertia?
Inertia is an object's resistance to change in its state of motion.
Inertia is the force that causes an object to move in a straight line.
Inertia is the tendency of an object to accelerate when a force is applied.
Inertia is the property of an object to remain at rest unless acted upon by an external force.
What is Newton's 2nd law of motion?
F = ma, where F is force, m is mass, and a is acceleration.
F = mv, where F is force, m is mass, and v is velocity.
F = m/a, where F is force, m is mass, and a is acceleration.
F = m + a, where F is force, m is mass, and a is acceleration.
THe equation to solve for momentum is P=MV. What does each part of the equation mean?
P= Momentum (units are kg* m/s)
M= Weight (in kg)
V = Speed (in m/s)
P= Force (units are N)
How can understanding forces help in sports?
It can help in improving performance by optimizing movements and techniques.
It has no impact on sports performance.
It only helps in understanding the rules of the game.
It is only relevant for strength training.
Using F=ma as a triangle what would the equation be to solve for the following; With what force will a car hit a tree if it's mass is 3,000kg and has a acceleration of 2m/s2?
f=ma
f=m/a
f=m+a
f=ma^2
Acceleration due to gravity is _______
9.8 m/s2
10.5 m/s2
9.0 m/s2
8.0 m/s2
Name 3 of the 4 types of friction.
Rolling, Sliding, Static
Sliding, Kinetic, Frictionless
Static, Dynamic, Fluid
Rolling, Sliding, Air
What is the difference between mass and weight?
Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.
Mass and weight are the same; both refer to the quantity of matter in an object.
Weight is the amount of matter in an object, while mass is the force of gravity acting on that matter.
Mass is a measure of an object's volume, while weight is a measure of its density.
